During the four-day symposium "Habitable Worlds Across Time and Space," scientists from diverse fields will gather at the Space Telescope Science Institute in Baltimore, Maryland, on April 28 through May 1, to discuss the formation and long-term evolution of terrestrial bodies throughout the various phases of stellar and Galactic evolution. ...

... We present preliminary results from two programs to image the host galaxies of radio-quiet quasars in 1.6 micron light using NICMOS camera 2 on HST. The high redshift program consists of QSOs covering the redshift range 0.8 < z < 4.4 and a range of QSO luminosities. Of the six objects for which data have been obtained the results range from no host galaxy detected, to an obvious galaxy with an interacting companion, to a possible high redshift galaxy cluster. ...

... Apache HTTP Server Version 2.2 . ... The term Virtual Host refers to the practice of running more than one web site (such as www.company1.com and www.company2.com ) on a single machine. Virtual hosts can be " IP-based ", meaning that you have a different IP address for every web site, or " name-based ", meaning that you have multiple names running on each IP address. ... If you are trying to debug your virtual host configuration, you may find the Apache -S command line switch useful. ...
